ECG + IHRN
What is ECG with Irregular Heart Rhythm Notification?
An electrocardiogram (ECG) is a test that measures your heart's electrical activity to create a recording of your heart rate and rhythm. The Irregular Heart Rhythm Notification (IHRN) feature periodically measures your heart rate and notifies you to take an ECG if it detects an irregular rhythm suggestive of atrial fibrillation.
How to use Irregular Heart Rhythm Notification
1. Download and install Samsung Health Monitor
To download and install Samsung Health Monitor:
1. Pair your Galaxy Watch to your Galaxy smartphone using Bluetooth.
2. Connect your Galaxy Watch to the Galaxy Wearable app on your smartphone and update the watch software.
3. Download the Samsung Health Monitor app from the Galaxy Store.
4. Open Samsung Health Monitor on your phone and set up your profile.
Note you must be at least 22 years old to use Samsung Health Monitor
After you set up your profile, you can set up the Samsung Health Monitor features that are available in your region.
2. Set up and record an ECG with your Galaxy Watch
To set up ECG:
1. Make sure you have the latest version of Samsung Health Monitor on your phone and Watch. It’s available from the Galaxy Store.
2. Open Samsung Health Monitor on your phone and tap ECG.
3. Follow the on-screen instructions.
Before you record an ECG:
1. You should be still for 5-10 minutes beforehand.
2. Make sure the sensor on the back of the watch is clean and dry.
3. Wear the watch snugly and away from your wrist bone so it lays flat.
4. Rest your arms comfortably on a flat surface.
To record an ECG:
1. On the paired Galaxy Watch, open Samsung Health Monitor and tap ECG.
2. Follow the on-screen instructions. Your result will be synced to the paired Galaxy smartphone.
Your ECG results
You may see one of the following ECG results:
Sinus rhythm: This result means that during the recording the heart was beating in a regular rhythm with a heart rate of 50–99 beats per minute (BPM). Caution: A Sinus Rhythm result does not guarantee that you are not experiencing an arrhythmia or other health condition. If you are not feeling well, contact your doctor.
Atrial fibrillation (AFib): This result means that during the recording the heart was beating in an irregular rhythm with a heart rate of 50–99 BPM. If you get this result, contact your doctor for guidance.
High heart rate: High heart rate means your heart rhythm was normal, but your heart rate was between 100 and 150 beats per minute. If you keep getting this result and your resting heart rate isn’t normally this high, contact your doctor.
Atrial fibrillation with high heart rate: Atrial fibrillation with high heart rate means the heart rhythm was atrial fibrillation with a heart rate between 100 and 150 beats per minute. If you get a result of atrial fibrillation with high heart rate, contact your doctor as soon as possible. A high heart rate can weaken the heart muscle and reduce its ability to beat properly.
Inconclusive: Your watch recorded a good-quality ECG, but the recording can’t be classified for one or both of these reasons:
- Your heart rate was lower than 50 or higher than 150 beats per minute.
- You had an irregular heart rhythm other than atrial fibrillation.
Poor recording: This result means the ECG app couldn’t analyze the data. A poor recording usually happens because your body moved during recording or the Galaxy Watch didn’t have enough skin contact with your wrist or finger. If you get this result, try again.
If you get this result, try again. If you keep getting this result, learn about things you can try to get a better recording. In the phone app, go to More options > Help > Troubleshooting
3. Turn on irregular heart rhythm notifications
How it works:
When the Irregular Heart Rhythm Notification (IHRN) feature is on, your Galaxy Watch will check your pulse a few times a day when you’re still.
Your Watch and phone will notify you if your Watch detects 1 hour of an irregular rhythm that suggests atrial fibrillation.
To turn on irregular heart rhythm notifications:
1. Record an ECG that isn't a poor recording.
2. Open Samsung Health Monitor on your phone and tap Get started on the ECG home screen.
3. Follow the on-screen instructions.
Your Galaxy Watch is not constantly looking for atrial fibrillation. This means your Galaxy Watch can’t detect all instances of atrial fibrillation. You may not get a notification even if you have atrial fibrillation. You won’t be notified for episodes of atrial fibrillation that last less than 1 hour.
4. Confirm irregular heart rhythm notification with an ECG
If you get an irregular heart rhythm notification, be sure to take an ECG as soon as possible so you have a more accurate record of your heart rhythm.
After you take an ECG, the ECG data is synced to the paired Galaxy Smartphone where a PDF report is created. Use the ECG result to decide whether to contact your doctor. You can view your detailed ECG results on the paired smartphone and share them with your doctor.
Things to know before using ECG:
1. The ECG app should not be used for any diagnostic purposes.
The ECG app cannot diagnose cardiac conditions or look for signs of a heart attack.
2. The ECG app is not meant to replace traditional methods of diagnosis or treatment by a qualified healthcare professional.
If you think you are having a medical emergency, contact your local emergency services immediately.
3. DO NOT change your medications or dosage without first consulting your doctor.
4. DO NOT interpret or take clinical action based on the ECG app measurements without first consulting with a qualified healthcare professional.
5. DO NOT use the ECG app if you have an implanted pacemaker, implanted cardiac defibrillator, or other implanted electronic devices.
6. DO NOT use the ECG app if you have known arrhythmia other than Atrial Fibrillation.
